My Environment there are two Sites with Exchange Server 2010: SiteA (Main) and finished the setup SiteB now.
I installed two server Multirole (cas/mbx/hub) with DAG and CAS Array. (SiteB)
The MBX servers there is one mailbox database each. (Mailbox Database 123456789 and Mailbox Database 098765432)
To remove this mailbox database i did the commands below:
Get-Mailbox -Arbitration -Database "Mailbox Database 123456789"
Out: no results
The system mailbox, federation mailbox and discover search are in other server (SiteA).
I removed the Mailbox Database 123456789 with success. But, the Event Viewer show Warning 1006, follow below:
The Microsoft Exchange Mailbox Replication service was unable to process jobs in a mailbox database.
Database: Mailbox Database 123456789
Error: Couldn't find system mailbox 'SystemMailbox{f251ed48-b560-437c-942a-b89cdeddfaaf}' in Active Directory.
Any idea if this is a issue and What to do?
